l 578,098, and in Germany March 27, 193i 10 Claims. (Cl. 131--43) Thisinvention relates to a cigarette rod machine with an adjustable guidefor the paper cigarette rod machines, wherein the ciga- 5 rette paperhas a relatively long guide, for exa e in machines wherein the tobaccois brought directy upon the paper, there is 'the clisadvantage the paperis not always in the correct position the place where the adhesive is sothat the strip of adhesive also is not always in the correct place. Itis already known to pass the paper strip, for the purpose of aligningit, through. a'guide before its introduction into the tipping andprinting apparatus, and to ineke the rpide laterally adjustable. This deI'ice is not immediately applicable for guiding the paper on itsintroduction to the adhesive-applying place, because at that place thepaper is already curved, a lateral displacement of the 9.o would causethe strip to tear.

in order to secure accurate positioning of the strip oi adhesive on thepaper, the guide for the paper, which part is provided iront of theplace where the adhesive is applied, is Aso arranged according to theinvention that it isrotatable about, or approximately about, the axis ofthe oigo ette The lateral edges of the paper strip may then be alignedrelatively to the adhesiveapplying apparatus rotating the guide.

One constructional example is shown in the accompanying drawings,wherein Figure l is a iront view, and

Figure 2 is a side view.

Figure 3 is a diagrammatical View of a part of a cigarette rod machineshowing the arrangement of the guide according to the invention incombination with other parts.

The paper strip a indicated in Fig. 3 by a dot and dash line is drawnofi from a roller m journalled in the machine frame M. The paper stripruns over a set of rollers m1 through the printing apparatus indicatedby the reference letter 1L and from here over another set of rollers n1into the U-shaped chute o arranged beneath the tobacco carding device,the under part of which is designated with the reference letter p. Thetobacco falls from the carding apparatus onto the paper strip within thechute o in the form of a thin lm and is conveyed with the paper strip.

An endless band t also indicated by a dot and dash line is guided overVa set of rollers u into a chute 'u forming a continuation oi the chuteo. This band receives the paper strip with the tobacco and forms it intoa rod. For this purpose an apparatus w is arranged which folds the endlit) of the paper strip by means of the band together, and the so foldedpaper strip containing the tobacco is brought to the adhesive applyingapparat s q which applies the adhesive to the vedge of the paper stripand then presses the paper edges together so that a cigarette rod sforms. This rod is afterwards cut into respective lengths by means notillustrated in the drawings.

The parts and the arrangement of the machine described until now are ormay be oi' known G5 construction. According to the invention iinprovedadjustable guiding means are provided for the paper s "lp before it isintroduced into the adhesive applying apparatus q. This irnprovedguiding means designated in Fig. 3 a 70 whole with the reference letter1' is illustrated in details in Figs. l and 2 oi the drawings.

The purpose of the improved guide .to providel an accurate adjustment ofthe paper strip before it enters the adhesive applying apparatus f5 andis provided with adhesive. The guiding means comprises a guide oradjustable member ZJ constructed U-shaped in cross-section The bottom iscurved and'corresponds to the shape which the paper strip assumes atthis place. The paper strip passes through the said guide b, be ing`held therein by two lateral plates c and d, which are fixed to the twolateral limbs of the U-shaped guide or member b by means of bolts e.`The bolts c are situated in slots in the limbs of the guide b, so thatthe plates c and d can be adjusted higher or lower, this adjustmentbeing` eiected in order to adapt the apparatus to dit-v ferent widths ofpaper. The plates are so adjusted that they guide the paper accurately,that is to say, they prevent the paper from rising to the one side orthe other. The guide b is provided with an extension'f, the lower faceof which has the form of a worm wheel, having its axis coinciding, orapproximately coinciding, with the axis of the cigarette rod which is tobe formed. The said worm wheel meshes with a worm g journalled in abearing bracket IL on the machine frame, and adapted to be rotated bymeans of hand wheel i. The guide b or its extension is likewiseguidedcin the bracket h, lateral pins lc on the extension f engagingarcuate slots m in the bracket h.

The paper strip on emerging from the guide b reaches theadhesive-applying place, where the adhesive is applied. v

The mode of operation oi the device is consequently as follows:

If the attendant of the machine observes that the adhesive is beingincorrectly applied, that is to say, that the adhesive applying rollermeets the paper strip either too far from the edge, or that the adhesiveis not applied in the correct Width upon the paper strip, he has merelyto rotate the knob z' in one or the other direction. The Whole guide bthen rotates in one4 or the other direction about, or approximatelyabout, the axis oi the cigarette rod, and consequently the paper stripis moved in one or the other direction relatively to the adhesiveroller, and is thereby brought into correct engagement with the adhesiveroller, without being moved out of the direction of the rod itself.

Of course, other constructional means may also be selected for guidingand adjusting the band, thus, for example, a guide in a cam, a helicalgear drive or the like may be used instead of the Worm Wheel. drive.

I claim:-

l, A cigarette rod machine comprising in combination with the means forguiding the paper strip and the means ior applying the adhesive to thepaper strip, an adjustable guide for the strip provided in iront or theadhesive applying means and means ior rotating said guide about an. axiscoinciding with the axis of the cigarette rod for the purpose to adjustthe guide.

2. A cigarette rod machine comprising in combination with the means iorguiding the paper strip and the means for applying the adhesive to thepaper strip, an adjustable guide for the strip provided in front of theadhesive applying means, a Worm Wheel provided on the guide, the axis ofWhich Worm Wheel coincides with the axis of the rod and a manuallyoperated Worm meshv ing with said Worin wheel for the purpose oirotating said Wheel and guide thereby adjusting the guide.

3. A device for adjusting the guide of a paper strip particularly forcigarette rod machines, comprising means for moving the guide around anaxis approximately coinciding with the axis of the cigarette rod toshift the paper strip to travel the desired path and position.

4. A device for adjusting the guide of a paper strip particularly forcigarette rod machines, comprising means for imparting a rockingmovement at right angles to the direction of travel of the paper striparound an axis approximately coinciding with the axis of the cigaretterod to thereby shift the strip to travel the desired path and position.

5.
